A short while ago, I occurred to me that there are 2 things that have not been asked about HDS lights.
1. exploded view: nobody wants to tear one apart simply to see what's in it?
2. light output: according to HDS, they hold output steady and allow runtime to vary. How is this accomplished during the manufacturing process? I have 2 theories:
a. the circuit regulates current, but allows it to vary in that the total watts consumed by the led remain constant from unit to unit. This would be a constant current regulator tuned to the specific Vf of the emitter. The problem I see with this is that luminous flux varies from led to led. You could have 2 lights with the same watt usage, but with vastly different light output.
b. each light is actually "tuned" with the help of a light meter. This seems to reflect the accuracy that we have become accustomed to from HDS, but it seems tedious, slow, and too expensive.
